Study Notes
Fossil Fuel Formation
- Fossil fuels, including crude oil, natural gas, and coal, are formed from the remains of plants and animals that died millions of years ago.
- This process takes a very long time, and the rate at which we're currently using these resources is faster than the rate of their creation.
- Fossil fuels are non-renewable resources, meaning they are not being replenished or are being made at a very slow rate, and once they are depleted, they cannot be replaced.
Crude Oil and Natural Gas Formation
- Millions of years ago, microscopic marine organisms and plants died and sank to the ocean floor.
- Layers of sediment covered these remains, increasing pressure and temperature over time.
- The remains were chemically transformed into crude oil and natural gas.
- This process required anaerobic (lack of oxygen) conditions.
- Oil migrated through permeable rock.
- It became trapped when it encountered impermeable rock.
- Oil companies extract oil by drilling through the impermeable rock.
- Crude oil is then processed into usable products like petrol and diesel.
Coal Formation
- Coal formed from dead plants approximately 300 million years ago.
- Plant debris accumulated in swamps or on seabeds.
- Sedimentation buried the debris, protecting it from air and slowing decomposition.
- The basin gradually sank, increasing temperature and pressure.
- Pressure and heat over millions of years transformed plant remains into coal.
Energy Classification
- Energy resources are classified as either renewable or non-renewable.
- Renewable energy sources replenish naturally (e.g., biofuels, geothermal, hydro, tidal, wave, solar, wind power).
- Non-renewable energy sources are depleted when used (e.g. fossil fuels, nuclear power).
Fossil Fuels: Coal
- Advantages: Cheap to mine, convert to electricity, lasts longer than other fossil fuels.
- Disadvantages: Atmospheric pollutants (including greenhouse gases) are produced when burned.
Fossil Fuels: Oil
- Advantages: Cheap to extract, used in industry and transportation.
- Disadvantages: Atmospheric pollutants (including greenhouse gases) are produced when burned. Limited supply.
Fossil Fuels: Natural Gas
- Advantages: Relatively cheap, Used for heating and cooking, cleaner fuel than coal and oil.
- Disadvantages: Atmospheric pollutants (including greenhouse gases) are produced when burned. Limited supply.
Nuclear Fuels
- Advantages: Does not produce carbon dioxide or sulfur dioxide when used.
- Disadvantages: Non-renewable, potential for accidents with radioactive waste.
Renewable Energy Sources
- Wind Energy: Capturing wind energy using turbines to produce electricity.
- Water Energy (Hydroelectricity): Using falling water to produce electricity. Wave energy, Tidal energy, Water power in dams are examples of water energy.
- Geothermal Energy: Using hot water and steam from the Earth's interior to produce electricity.
- Solar Energy: Harnessing sunlight to produce electricity (solar panels) or for heating (solar panels).
Biofuels(Biomass)**
- Using plant or animal waste to generate energy.
